Vastly simplify unit tests for mos6502
...
Criterion's init and fini config options allow us to register setup and
teardown functions. We now use this to register the common cpu variable
for the mos6502 tests, albeit through the use of a global variable.
Doing so necessitated that each of the different test files have their
own suites, due to some implementation details in Criterion, but this is
No Big Deal.

Remove cycles field from mos6502 struct
...
It was both unused and not necessary, as we can simply compute the
number of cycles in the execute function.

Add the execute function for the 6502
...
This executes a single opcode. Note this also makes a change to the
get_address_resolver function such that accepts an opcode, not the
address mode itself.

Zero out last_addr and cycles
...
This fixes a super-annoying bug in the unit-test suite where we would
fail randomly because sometimes last_addr would have garbage in it.
